About MCS

MCS is a mark of quality and demonstrates
compliance to industry standards that companies
strive to meet. It highlights to consumers that
companies are able to consistently install or
manufacture to the highest quality every time.

The Ecodesign of Energy-related Products (ErP) Directive came into force on 26th September 2015. MCS Heat Pump standards were updated to be in line with the directive.

Installer Standard: MIS 3005 v4.3
Product Standard: MCS 007 v5.0

A transition period has been in place since 26th September for Heat Pump products, however from 26th March 2016 a Heat Pump product must comply with MCS 007 v5.0 to remain MCS certified.
